Description
Technical field
The utility model relates to automobile product diel field, more specifically relates to the shaping drawing mechanism of punch level progressive die.
Background technology
A large amount of parts on existing automobile are generally stamping parts, therefore, need a large amount of moulds shaping.But, some Workpiece structure is special, and curved surface is more and complicated, such as, automobile panel, this part generally all has complementary surface characteristic, each parts has upwards or to compacted under, and is the subsidiary curved surface forming in border, so in curved draw forming process, just require that mould structure is practical, and stability is high, what could meet product goes out yield.For guaranteeing the product quality of the profiled member of tablet, after tablet is compressed by blank holder in the punching course of mould, punch-die redraws distortion, final formation shape of product, and then by blank holder, tablet is departed from from punch, because in automatic stamping, mechanical stamping speed reaches 12 beats/min, so when upper and lower mould is separated for be separated instantaneously, tablet has kind of an inertia motion when upper/lower die is separated, and causes beating of tablet, and the position of tablet on mould is not fixed.
Utility model content
In order to solve the problem, the shaping drawing mechanism of the tablet not easily punch level progressive die of off normal when the utility model provides that a kind of pressure-pad-force is stablized, upper and lower mould is separated.
According to an aspect of the present utility model, provide the shaping drawing mechanism of punch level progressive die, it comprises upper bolster, upper die forming die, counterdie drawing punch, die shoe, blank holder, blank holder stopping means and drive unit, upper die forming die is fixed on upper bolster, counterdie drawing punch is fixed on die shoe, blank holder is positioned at the outside of counterdie drawing punch, the bottom connecting drive device of blank holder, blank holder stopping means is installed on die shoe, drive unit drives blank holder to move up and down, the stroke that blank holder stopping means restriction blank holder moves up and down.Thus, when mould matched moulds, drive unit acts on blank holder, and make blank holder arrive the extreme higher position of blank holder stopping means, blank holder is subject to the gravity from patrix, and blank holder pushes down material strip together with the edge of upper die forming die; Patrix continues to move downward, push down blank holder down to move, counterdie drawing punch contact material strip starts drawing, material strip is subject to starting distortion from the pulling force of counterdie drawing punch, the material of whole drawing station shrinks inwards, until blank holder is depressed into the extreme lower position of blank holder stopping means, material strip flowing drawing and moulding is made to be net shape; When mould die sinking, punch press drives part of the upper die to move upward, drive unit acts on blank holder, and blank holder is moved upward from the extreme lower position of blank holder stopping means and arrives extreme higher position, blank holder is in binder state always, after blank holder arrives extreme higher position, stop buoyant action, punch press drives part of the upper die to continue to move upward, and whole product is separated lower mold assemblies completely, inertia motion when product can not be separated by upper/lower die causes beating of tablet, good stability.
In some embodiments, drive unit comprises nitrogen jacking block and nitrogen assembly, and the top of nitrogen jacking block connects blank holder, and bottom is connected with nitrogen assembly.Thus, nitrogen Component driver nitrogen jacking block moves up and down, and nitrogen jacking block drives blank holder to move up and down.
In some embodiments, die shoe is provided with bottom seat pad, and bottom seat pad is connected with base plate, and nitrogen assembly is installed on base plate.
In some embodiments, die shoe is provided with nitrogen jacking block via hole, and nitrogen jacking block runs through the nitrogen jacking block via hole of die shoe.
In some embodiments, blank holder stopping means comprises the spacing hook of blank holder and kills block, the spacing hook of blank holder and kill block and be all installed on die shoe, and blank holder moves up and down at the spacing hook of blank holder and killing between block.Thus, during matched moulds, blank holder moves downward and touches when killing block, and blank holder arrives extreme lower position; During die sinking, blank holder moves upward and touches the spacing hook of blank holder under the effect of nitrogen assembly, and blank holder arrives extreme higher position.
In some embodiments, the bottom of blank holder is provided with guide pillar, and die shoe is provided with guide pin bushing, and guide pillar is arranged in guide pin bushing.Thus, blank holder, in the process moved up and down, is led by guide pillar guide pin bushing, accurately locates when blank holder is moved.
In some embodiments, the top of blank holder is provided with guide pad.Thus, guide pad be used for lead material strip, make material strip accurately arrive specify location.
In some embodiments, nitrogen backing plate is provided with between nitrogen assembly and base plate.Thus, because nitrogen assembly during punching press is stressed comparatively large, nitrogen backing plate is set and prevents bottom slab stress to be out of shape.
In some embodiments, between upper die forming die and upper bolster, be provided with upper padding plate, between counterdie drawing punch and die shoe, be provided with lower bolster.Thus, by the height of adjustment upper padding plate, lower bolster, the requirement of mold stroke can be met.
The utility model has the advantages that: the utility model is rational in infrastructure, during matched moulds, nitrogen assembly acts on blank holder, blank holder is made to float to the spacing hook of blank holder, blank holder arrives extreme higher position, blank holder is subject to the gravity from patrix, and blank holder pushes down material strip together with the edge of upper die forming die; Patrix continues to move downward, push down blank holder down to move, counterdie drawing punch contact material strip starts drawing, material strip is subject to starting distortion from the pulling force of counterdie drawing punch, the material of whole drawing station shrinks inwards, until blank holder is depressed into kill block, blank holder arrives extreme lower position, makes material strip flowing drawing and moulding be net shape; When mould die sinking, punch press drives part of the upper die to move upward, and nitrogen assembly acts on blank holder, makes blank holder move to the spacing hook of blank holder from killing block, blank holder is in binder state always, after blank holder arrives extreme higher position, stop buoyant action, punch press drives part of the upper die to continue to move upward, whole product is separated lower mold assemblies completely, inertia motion when product can not be separated by upper/lower die causes beating of tablet, good stability, and product goes out yield and improves.
